My invention relates to shipping cases, and particularly to shippingcases adapted to serve ask parcel post laundry cases or containers. Y IOne of the objects ofthe invention isfto provideV a simple, practical,and advantageous. form of shipping case.

AAnother object of the invention is to pro-k vide an advantageousconstruction of ship- 'ping case involving an inner sti box or containermade of material similar to cardboard, pasteboard, or the like, and anouter case or cover preferably made of a flexible fabric such as canvasor like material.

Another object of the invention is to pro# vide a construction of innerbox or case which y may be inexpensively inadein quantity, and f whichwill be stiff and rigid enough to strongly resist outside pressure.Another object` of the invention is to provide a construction of outercase or cover-.

ing, which may be advantageously and inexpensively made, and which willreadily accommodate a stiif inner box or case.

Another object of the invention is to provide an advantageous materialfory making the stiff inner box or case.

Another object ofthe inventionis to afrrange for the `making of theouter case or.

cover from a single material. y

Another object of the invention is to arpiece of fabric or like rangefor effective tightening of the outer case or cover on thevr inner caseor box.

In Fig. 4 I show this inner case or box 2 by itself-that is, without theouter case orl cover 1.

The outer case or cover l is preferably made` of a single piece ofmaterial bent and sewed to make the case by a method or process whichwill be later referred to. In its completed form, however, this outercase or cover `1 aps pears as shown in Figs. 1, 2., andB, inwhich itcompletely encloses the inner box2 cover- Y515 Referring to the drawingsI show in Figs..

The

as a handle for carrying t-he device. construction of this outer case orcover 1,

will be best understood by referring to Figs.

5 to 12 inclusive, showing the manner in which the same is made, and toFig. 13, showing the completed device. i u Y In Figs. 5 to 12 al singlepiece of material in the form of a rectangular blank 5 is shown,

and from this blank the case or cover 1 is made by folding and stitchingin a certain manner. spread out and in a flat condition. n blank arefastenedor secured certain strips o-r the like, and these strips orstraps become the straps 3 previously referred to as shown In Fig. 5this blank 5 is shown In this f 90.*.,

or straps of material such as webbing leather l by sewing, to theundersideof vblank 5, and

therefore appeared in dotted lines in Fig. 5.

At one end for example, the lower end ofeach,y

Vacs

strap 3, there is a buckle 6, and the other end of Veach strap forexample, the upper end is adapted to lit and work in the correspondingbuckle 6, said upper ends preferably provided with metal end pieces orclips 7.

The blank 5 is provided with certain lines or markings where it is to befolded, andv where it is to be sewed as will be described. At its lowerend, the blank is provided at its corners with diagonal lines 10, andvertical lines 11, and cross or horizontal lines 12. At its middleportion, it is provided with oppositely inclined horizontal lines 13 andvertical or longitudinal lines 14, and cross `or horizontal lines 15 and16. At its upper end the blank is provided with diagonal lines 17similar to lines 13 and cross lines 18, and vertical or longitudinallines 19.

First the blank is folded along lines 1111 by moving the outer cornerportions 20 and the outer edge portions 27 upwardly, and then downwardlyso as to fold such portions 20-27 down substantially over the bodyportionv of the blank, making creases 21--21 as shown in Fig. 6. Lines10e-10 will then appear in reverse position as shown in said Fig. 6.

' Next the corner portions 23 are 'folded about the lines 1010, so thatthese corner portions 23 will lie flat upon the bottom portion of theblank as is shown in Fig. 7. The corner portions 20 are doubled Vunderthe portions 23 as shown in said Fig. 7 Stitching or sewing is thenextended along the edges 23a, so as to secure said edges to sideportions27.

Next the bottom portion 22 is 'swung' upwardlyy so that it assumes asubstantially vertical position, that is, an upright positionconsidering that the blank 5 is still in a iiat position. This portion22 swings up about a line 12a extending between the lines 12-12.

As this vmovement takes place, the stitched edges or corners 23a swingoutwardly and upwardly and the side portions 27 also swing outwardly andupwardly so that the bottom portion 22 and the side portions 27 -27 formupwardly extending rim portions at right angles to one another, and theseams 231--232L form rectangular corners between said portions 22,27-27,as shown in Fig. 8. The portions 23 which were folded down now assume anupright position and the corner portions'20 are doubled back uponthemselves in loop form, as shown in said Fig. 8. Tape 26 is stitchedalong the edge of upright portion 22, and around the cornersf23n4 so asto bind the edge of said portion 22, and also hold the corners 23a andparts forming the same together. This tape 26 will hold the loopedportions ofthe corners 2O against the edge portion 22.

Next the material is foldedalong diagonal lines 1313, the result ofwhich is to move orswing the upper portion of edges 27 upwardly so thatsaid edges 27 will stand'in a` substantially vertical or uprightposition from their lower ends to the lines 13, as shown in Fig. 9. Atthis time lines 16 will extend vertically upward, and will be superposedupon or in contact with lines 14, which latter will extend up verticallyas will also the material of the blank between vlines 14, said materialbeing drawn or pulled upwardly by the folding of the blank about linesV13. Stitching or sewing will then be extended along the aligned lines16-14, and thus a structure will be made or formed with a bottom 5a, alower upright wall 22, side upright walls 27-27, and a top upright wall28, all as shown in said Fig. 9.

Next the blank is folded along the lines 18-18 and intermediate line 18aso that the y along the edges 18-18 formedV along lines Next themarginal or edge part 30 is swung upwardly so as to formv asubstantially upstanding or vertical edge Yor wall portion 30,V

as shown in Fig. 12, the vside portions 33 also extending up verticallyadjacent to the wall 30, so that a structure with upright end wall 30and side wall and side upright walls '3"- 33 is formed. Tape 34 ispreferably applied also along the along the edges of wall 30 and side ofwalls 33. Y

Thus, the blank vshown inFig.VV 5',a sin- -gle piece of rectangularmaterial such as canvas or other fabric may beform'ed into an outer caseor cover, such asshown in Fig.V

12. In this arrangement the lower part of the device illustrated by therectangular structure, having walls 22 and 27, isto receive the innerrigid case or b oxsuch as the structure shown in Fig. 4. The upperportion of the arrangement shown in Fig. 12, is to be folded down andvused to cover the top of the inner'caseV 2 which, yotherwise is to beexposed and to 'be drawn Vandheld `firmly and tightly about the same'.V

In Fig. 12 this outer case or cover is shown f ready to receive theinner box or case, and to A have its upper portion folded down over the"same. In Fig. 13 this outer `case or cover is shown, still empty orwithout the inner box,

but with its upper portionl swung or foldedv down so'as to almost closethe lower portion.

This Fig. 12 shows the outer case or cover which we have described so inldetail in the process of' making. The various 'parts and featuresdescribed in connection with Figs.

. 5 to 12 inclusive will appear and at once be vrecognized in this Fig.13.- The receiving portion or holder 35, havingthe upstanding Y walls22, 27-27 is shown below the upper covering portion 36, which latter isswung about the line 152L in order that the upper or cover portion 36maybe moved and pulled down over the lower receiving portion 35. Thestraps or strips 3-3 are then in a depending position, as shown in Fig.13, and the strap 4 is in a position ready to be connected with thebuckle 4a of another strap 4b. These two straps 4 and 4b are secured asby stitching to corner or angular formations 38, which are at the backend of the structure, as shown in Fig. 13, which portion of thestructure, however, becomes the top when the device is in position forholding or carrying or resting as shown in Fig. 1. These portions 38 areformed by the projecting ears shown in Fig. 9 which develop at themiddle of the cover blank, when the same is bent by lines 13-13 asdescribed in connection with Fig. 9,

and is also shown in Fig. 12. When the upper or cover portion 36 of thecover is swung down a bit, the projecting portions may be bent towardone another so as to form the ears or flaps 38, and these may be foldeddownand against the adjacent part of the case as previously referred to.f

The inner box or case 2, shown particularly in Fig. 4 may be of anypreferred or desired construction to go with the outer case or cover 1.However, I show a highly advantageous form of construction in Fig. 4,which involves a box made with a body portion 2a and a pair of hingedcover aps 2", which have their meeting edges preferably cut so as todove tail or mortise as shown in Fig. 4, one part being provided with arecess 2c and theother with a tongue 2d, whichrts in, but overlaps therecess 2, the end portions 2e, overlapping the adjacent portions of theother cover secy tion, so that an interlocking arrangement is secured.This makes a firm and rigid wall for the inner box or case, whichstrongly resists external pressure. If desired, the other side of thecase or box 2 may be made in a similar manner as illustrated in dottedlines in Fig. 4.

While the boX or case 2 may be made of any suitable material, Ipreferably make it ofv a material which I find to be particularlyadvantageous byreason of its strength, rigidity and Workability. Thismaterial consists of a central chip filler 46, and outer cylinder kraftliners 47. This practically doubles the Mullen test strength of the box,and also practically eliminates the breaking point, that is the materialmay be bent back and forth on its scoring marks without breaking theliners.

'To assemble the complete device, inner box or case 2 is placed in thereceiving portion 35 of the outer case or cover 1, and then the upperportion 36 of said case 1,is swung or folded down so that it will coverand enclose the box receiving or inner portion 35. The device thusarranged is shown in Figs. 1, 2, and 3.

The encircling straps or strips 3 3, have their ends fastened togetheras by passing the metal end pieces 7, 7 throughl the buckles-6,16,

andV then pulling strongly and firmly uponv the endsfof said straps3, soas to tighten them aroundthe device. y y

These straps or strips 3 are preferably sewed to the top member 38, downto nearly the lower edge of the wall 30, as shown in Fig. 13, so thatwhen said straps are tightened, the

tightening pressure or pull is exerted practically at the yedge of wall30, and thus substantially the entire width of said wall is pulled ortightened, thereby preventing any wrinkling or looseness on the part `ofsaid wall.

Middle 'parts of the portions of the strips 'l or straps 3-3 whichextend across the top` member 36, are also preferably left unsewed.as-shown in Fig. 13, thereby leaving short, unfastened or unsecuredparts of said strips vwhich form slots or Asockets for receiving the endportions 40 of a frame or holder 41, for-a shipping tag-42. Theends 40of this frame or holder 41 are preferably reduced in width so as to benarrower than thebody portion ofasf;

frame 41, thereby forming shoulders 43 on f frame 41, so that whentongues 40 are pushed underneath Vloose portions 3a of straps 3, saidframe or holder 41 will be held in position by the straps 3, and thisholding or retention will be 'firm and 4secure when the straps 3aretightened by theirA vbuckled ends. When said straps 3-are not tight,however, the'holder V41 maybe removed by withdrawing its tongue ends40g-and the cardor shipping tag42may be changedv or 2replac'edfasdesired.A In-this Waya very si1nple,inexpensive, and effectiveconstruction is provided for holdinglthe shippingtgilg and its holder,and for manipu- Y latinjg the same so asto -make any change or mayf alsoserve as a handle for lifting and carryingth'e' device." Y

By tightening the strap 4 and members 38,

` a further effective pulling strain is applied to thecover 1, due tothe fact that these memv bers 38 are triangular or pointed in shape, andtheir outer ends are substantially the width of the small ends of thedevice, whereby the tightening of strap 4 will apply strong Y pressureto boththe upst-andingends of the device, and also to the bottom of thesaid ends. i Y

Thus, a very advantageous case is provided with a cover which may bemade of a single piece of material which can bel readily apy plied tothe inner boxlike structure, and may be readily tightened and lirmlysecured for shipping, and With a simple and inexpensive form of shippingtag holder, and at the same j time a stid inner box or case may beprovided in a very simple, practical, and inexpensive manner. i

It will be understoodthat changes may be made Without departing from thespirit of the invention.
